Canada bluegrass is a widespread, but introduced, North American plant.

Identification: This grass is 12-24" (30-60 cm) high.
Its culms (stems) are green or grayish blue, and relatively flat. Leaves are up to 4" (10 cm) ×
⅛" (4.5 mm), also bluish in color. In cross section, the leaves may appear fairly flat
or V-shaped, and leaf tips are shaped like the keel of a boat.
Where they attach to the culm, they wrap around it for a length of about an
inch. The stem tips are topped by a flowerhead that is described and drawn as sparse by
some sources, and denser by others. It is about 2-5" (5-12 cm) long and
1-2" (2.5-5 cm) around.
